Reca Weight At Age Report (ReportFdaWeightAtAgeData)

A list with two members: 'MeanWeightByAge', and 'GroupingVariables'.

MeanWeightByAge

A ReportFdaData table with reported <Statistic> being 'MeanIndividualWeight': the mean weight

GroupingVariables

Any specified Grouping variables.

Units are configurable, and can be inspected by ~getUnit

'GroupingVariables' is a data.table with a column containing the names of any aggregation variables.
